Stock LS6 heads and cam able to pass smog? If I bolted stock LS6 heads onto my LS1 and through in a LS6 cam, would I still be able to pass smog? Btw, I'm in Cali.
I'm just trying to do a real budget build and stay smog leagal (for now): LS6 heads, LS6 cam, Edelbrock shorties, SLP y-pipe, LS6 intake, ported TB, elec cutout.
Already have the K&N FIPK and catback. Later down the road, I'll go all out.
Thanks for the responses.

There are a few places to go for a tune...I have heard good things about both Ryne @ CMS and Rob @ Strictly.

The LS6 intake doesn't have a EGR port.. you will need to get the SLP adapter and make sure your shorties also has the EGR and AIR port connected.
Being that the LS6 engine (head and cam) are OEM for the Vette, it should pass the sniffer test as long as everything is working ok with sensors and PCM.
Many are passing with more cam than the LS6.. most will say a 224 will also pass, might consider that also.

224, really? Wow, if that's true, I'm going to get a TR224, that's what I wanted to begin with.

There are other cams that are in between the LS6 cam and 224 cams. That would give you at least 20 more rwhp than an LS6 plus better torque down low. Such as the CheaTR cam that drive and idles like stock.
Also consider milling the heads and/or running thinner gaskets for more compression and less quench height, that will help with efficiency and emissions.

I've been told that if you want to get away with the TR224 cam and pass a sniff, use a 114 LSA instead of 112. Won't be as lopey, but still makes the power, and still noticeable that you're running a cam.

Now I'm not sure how things are run in Cali, but I would think it's pretty much the same as other places, just stricter rules. Out here, most places don't do a visual other than look for cats under the car (and when I've watched my car go through sometimes they don't even check for them). I have a '00 T/A running an LS6 intake manifold without the SLP adapter and a TR224 cam - I had that EGR and AIR **** ripped out of it years ago. I just had the tuners delete and turn off all the codes for EGR and AIR so that the system doesn't pick them up. Cars '93 and newer with the OBDII plug don't get sniffed anymore (at least out here, maybe they still sniff in Cali...), they just plug the system into the PCM via OBDII and look for codes. No codes = all's good.

They check for EGR and AIR hookups too. Ive heard of people getting away with EGR by getting a 2000+ sticker showing no EGR in the engine compartment, but IDK if that really works.

The are much more stricter here in California. Depending on the smog shop and who is doing the check. They sometime will just gloss over the visual (but i would not count on that happening). They are now even checking the tank and EVAP/Canister system for leaks now, as of this year.
Just ask your friends as to where they get there smog checked.
If you get a good tuner, using the TR224 with a 114LSA..you should pass. But like the other say.. there are many mild to mid cam that if tuned, will pass.
